A rider has accused under fire Olympian dressage star Charlotte Dujardin of calling her horse a "b****" in a new video."

The equestrian star was at Stoneleigh show ground, Warwickshire, when her horse jerked its head up.

A video shows Charlotte pulling the horses head down with her reins and she can be heard appearing to say "you b***h"."

The video was filmed in September 2016 and shocked the steward filming - who had previously looked up to the star.

The woman, who wishes to remain anonymous, said: "I was around her a lot."

"I was taking a video at the time."

"I've not been a fan of her since that video."

"I had looked up to her since I was younger."

The woman was appalled by the recent footage released - showing Charlotte whipping a horse.

She said: "It is absolutely awful."

"I've had horses my whole life."

"It's the completely wrong representation of the horsey world."

"They are treated like absolute princesses."

Charlotte Dujardin has declined to comment until the investigation process is complete.
